Lake Chad, also known as Biwa in the Kanuri language, is a historically significant body of water located in central Africa, bordered by Nigeria, Niger, Chad, and Cameroon. Once one of the largest lakes in Africa, it has experienced significant shrinkage over the past several decades due to a combination of climatic, environmental, and human factors.
The lake’s basin covers an area of approximately 2,500,000 square kilometers (970,000 square miles), making it one of the largest endorheic (closed drainage) basins in Africa. Historically, Lake Chad has been an essential water source for millions of people living in the region, supporting fishing, agriculture, and livestock herding. It has also served as a crucial habitat for various wildlife species.
One of the primary tributaries feeding Lake Chad is the Chari River, which originates in the Central African Republic and flows through Chad before reaching the lake. However, the lake has no outlet, leading to high levels of evaporation under the intense heat of the Sahelian climate, especially during the dry season.
The lake’s water levels have fluctuated significantly throughout history due to natural variability in rainfall patterns and the balance between inflow and evaporation. However, in recent decades, Lake Chad has experienced unprecedented shrinkage, with studies attributing this decline to a combination of factors such as climate change, overuse of water resources, and population growth.
The shrinking of Lake Chad has had severe consequences for the surrounding communities, leading to conflicts over dwindling water and land resources. It has also exacerbated food insecurity and poverty in the region, as many people depend on the lake for their livelihoods.
Efforts to address the challenges facing Lake Chad include initiatives aimed at promoting sustainable water management, restoring ecosystems, and improving resilience to climate change. These efforts often involve collaboration between governments, international organizations, and local communities.
One notable example is the Lake Chad Basin Commission (LCBC), established in 1964 by Cameroon, Chad, Niger, and Nigeria to oversee the sustainable development of the lake and its basin. The commission works to implement projects related to water resource management, environmental conservation, and socio-economic development in the region.
Other initiatives focus on promoting alternative livelihoods for communities dependent on the lake, such as promoting drought-resistant crops, sustainable fishing practices, and eco-tourism. Additionally, efforts to improve irrigation techniques and water efficiency aim to reduce the strain on Lake Chad’s water resources.
Despite these efforts, the future of Lake Chad remains uncertain, as the region continues to face challenges such as climate change, population growth, and political instability. However, ongoing research, collaboration, and innovation offer hope for the sustainable management and conservation of this vital natural resource.

Lake Chad, situated in the Sahel region of Africa, holds considerable ecological, economic, and cultural significance. Its basin spans parts of Nigeria, Niger, Chad, and Cameroon, encompassing diverse landscapes ranging from wetlands to semi-arid savannas. Historically, Lake Chad has been a lifeline for millions of people, supporting agriculture, fishing, trade, and transportation.
At its peak around the 1960s, Lake Chad covered an area of approximately 25,000 square kilometers (9,700 square miles). However, since then, it has shrunk dramatically, losing over 90% of its surface area due to a combination of factors. These include prolonged droughts, increased water abstraction for irrigation, population growth, deforestation, and the impacts of climate change.
The Chari-Logone river system is the primary source of inflow to Lake Chad, providing about 90% of its water. The Chari River originates in the Central African Republic and flows through southern Chad before joining the Logone River and entering Lake Chad from the south. Other smaller rivers and streams also contribute to the lake’s water supply.
Lake Chad is a critical habitat for a variety of flora and fauna, including migratory birds, fish species, and aquatic plants. It supports a rich biodiversity that sustains local livelihoods and provides ecosystem services such as flood control, water filtration, and carbon sequestration.
The lake’s decline has had profound socio-economic consequences for the millions of people who depend on it for their survival. Communities around Lake Chad face challenges such as food insecurity, loss of income, displacement, and conflict over dwindling resources. These challenges are exacerbated by factors such as poverty, political instability, and limited access to education and healthcare.
Efforts to address the crisis facing Lake Chad are multifaceted and require collaboration at local, national, and international levels. The Lake Chad Basin Commission (LCBC), established in 1964, plays a central role in coordinating regional cooperation and implementing sustainable development initiatives. Member countries work together to manage water resources, conserve ecosystems, and promote socio-economic development in the region.
One of the key strategies for addressing the lake’s decline is the promotion of integrated water resource management practices. This includes initiatives to improve water efficiency, reduce pollution, and regulate water abstraction for agriculture, industry, and domestic use. Implementing such measures requires balancing the needs of different stakeholders while safeguarding the long-term sustainability of Lake Chad and its basin.
Environmental restoration projects aim to rehabilitate degraded ecosystems, such as wetlands and floodplains, to enhance biodiversity and ecosystem services. These efforts involve reforestation, soil conservation, and the establishment of protected areas to preserve critical habitats and wildlife corridors.
Investments in alternative livelihoods are essential for reducing dependency on Lake Chad’s dwindling resources. This includes promoting sustainable agriculture, aquaculture, and livestock farming practices that are resilient to climate change and contribute to food security and poverty alleviation.
International support and funding are crucial for scaling up efforts to address the complex challenges facing Lake Chad. Donor agencies, non-governmental organizations, and multilateral institutions provide technical assistance, financial resources, and expertise to support sustainable development projects in the region.
Despite these efforts, the future of Lake Chad remains uncertain, as ongoing environmental degradation, population growth, and climate variability continue to exert pressure on its fragile ecosystems. Sustained commitment and collaboration are needed to ensure the long-term resilience and vitality of Lake Chad for future generations.
